In this study a Minolta CR-300 colorimeter was employed. This is a handheld instrument that filters the reflected light to obtain color values (Hunt et al., 1991). In Fig. 2 the colorimeter is seen while performing a measurement of a calibration plate. Measurements are influenced by the light spectrum, which can be expressed as the color temperature. It was chosen to use the D65 lightning for the colorimeter.
The measurement head of the colorimeter covers a circular area with a diameter of 11 mm and the measurement sites on the sample are chosen by the operator. These sites are chosen depending on the sample,e.g. to avoid meat tendons and intramuscular fat.
